What reviewers complain about
!
The Black Labyrinth is an entry-level tour — and reads like one to adrenaline seekers.
The most detailed critical review of the Labyrinth is about time: about 1 hour 10 minutes inside the cave, the “fun part” around 20 minutes, the rest going to instructions, wetsuits, the drive to the cave and waiting for the group. It is a guided float with a couple of backwards jumps, not an extreme sport — ropes, heights and a physical challenge are what the Black Abyss adds. Match the tour to the day you actually want.
Three more points are worth knowing. The cold: the cave water stays cool all year, and on the Black Abyss the cold comes up in several reviews, one of them from February, midsummer in New Zealand — the wetsuit helps, the hot shower afterwards helps more. The photos: personal cameras are not allowed on either tour, and the pictures the guides take are sold separately afterwards — one critical Black Abyss review takes issue with the ban. The group size: Labyrinth departures run with up to 12 participants, the Abyss with up to 8, with a fixed rhythm to match.
And the praise, for balance: on both tours the positive reviews keep coming back to the guides and to the float under the glowworms in complete darkness.
So which one do you actually want?
You want the Black Labyrinth if this is your first time underground. It delivers the whole black water rafting idea — the river, the jumps, the glowworm float — in three hours, without ropes and without a fitness bar to clear. It is also the only option when someone in your group is between 12 and 15, and the safer call if you are unsure how you handle dark, enclosed spaces.
You want the Black Abyss if the adventure is the point. The 35-metre abseil is the real thing, the zipline runs through a glowworm gallery in total darkness, and the waterfall climbs at the end ask something of your arms and legs. Book it when the whole group is 16 or older, reasonably fit, and happy to spend five hours on it.
You want neither if you mainly want to look at glowworms. That is not a consolation prize: the quiet boat tour through the Waitomo Glowworm Caves shows you the same phenomenon warm, dry and with no age gate — our sister site Glowworm Caves compares those tours. Wet or dry is the real first question, before Labyrinth versus Abyss even comes up.
★
In short
If you want the classic glowworm tubing trip, book the Black Labyrinth. If you want ropes, heights and a physical challenge on top of it, book the Black Abyss — provided the whole group is 16 or older and reasonably fit. If anyone in the group is 12 to 15, the Labyrinth is the tour you can all do together. And if you would rather stay dry, take the glowworm boat tour instead.
